Abstract:: Available phosphorus in 0-20 cm surface soil is studied in 855 State farm of Heilongjiang Reclamation Mudanjiang Branch Bureau, and historical data was compared with present data for various types of soil phosphorus conditions. The result of the change shows that farms phosphorus fertilizer use efficiency in the early is higher but is lower in late stage, leading to phosphorus accumulation in the soil, and increase the soil phosphorus content. Based on the project, the ‘3414’ data in recent years were analyzed to determine the farm soil phosphorus on the abundance deficiency indexes of various crops. And it plays scientific and rational guiding role in fertilization, fertilizer for the farm to provide scientific and rational decision-making.
